Electric tool

A hand-held power tool comprising:

• a tool body,
• a motor housed in the tool body,
• a grip part configured to be held by a user so that a predetermined operation is configured to be performed on a workpiece by a tool bit rotationally driven by the motor,
• a clutch that transmits torque and interrupts torque transmission between the motor and the tool bit,
• a non-contact torque sensor that detects torque acting on the tool bit during operation, no portion of the non-contact torque sensor being in physical contact with a torque detecting shaft that rotates together with the tool bit,
• a clutch control system that controls coupling and decoupling of the clutch according to a torque value detected by the non-contact torque sensor, and
• a mechanical torque limiter that is configured to prevent overload on the tool bit, the mechanical torque limiter being disposed in a torque transmission path between the motor and the tool bit,
• wherein a plurality of intermediate shafts are provided between a drive shaft driven by the motor and a final output shaft to which the tool bit is mounted, and the non-contact torque sensor and the clutch are disposed on different intermediate shafts.
